That's interesting. Is it like PowerTop in that it's just developed by Intel, but works fine on AMD platforms as well?

It says it will use the Intel specific drivers when available, when it can't use those then it will use the standarized x86 registers and the generic cpufreq infrastructure. Last line of the quoted text in the article.

It doesn't really tell me anything. "latest cooling and P state drivers developed by Intel" does not necessarily mean Intel-specific. Although I didn't see a P-state listing in PowerTop on my AMD hardware, so I suppose it is Intel-specific? And I also have no clue what what the x86 register use means in this context.

I'm assuming that Intel didn't develop drivers for AMD hardware, not really their style. So, yes, its Intel specific until AMD drivers are upstreamed and the daemon is patched to be aware of them.

The register comment would imply that part of the x86 standard is defining a specific set of CPU registers that say "When this register is this, it means: go to xyz performance state." So somewhere there is a register, lets call it PowerLevel (i know its not) and when its set to 1, thats idle, 2 is low power, 3 is medium, 4 is high, and 5 is turbo. And this daemon can set specific registers to specific values to help control the temperature of the box.
